Definitions

  • the present invention relates to the field of firearm sights, more particularly, to an electronic firearm sight with a touch display screen, which allows the shooter to adjust the reticle on it.
  • a reticle is a very important factor to locate the target.
  • Other auxiliary aides such as measuring the range, can be also used.
  • the existing firearm sight including the two types described above and an electronic sight uses two devices to adjust the reticle. One is controlling the reticle to move vertically so as to make it superimposed on the bullet's impact point, namely up and down; the other is controlling the reticle to move horizontally, namely left or right.
  • these adjusting methods have the following shortcomings:
  • the existing sight either mechanically or electronically, all set two buttons or knobs to make the reticle move.
  • these devices all preset a rated value as a moving scale.
  • the moving unit is rated, which represents a fixed value of the movement of the reticle.
  • a certain bullet impact point t does not have to be one of these fixed moving scales; as a result, the reticle can only be superimposed on the bullet's impact point approximately, but can not fulfill the full superimposition theoretically.
  • the shooter could encounter a target at the range of more than one thousand yards, but usually the superimposition of the impact point and the reticle can only be done within a very short distance, such as one hundred yards. Therefore, once the distance is over one thousand yards, the error value of the approximate superimposition will be quite big, which brings a lot of inconvenience to firing if highly accuracy is required
  • a telescopic sight can only use one reticle shape, which causes big limitation to shooting, because the different types of firearms, bullets, and shooting environments in practical shooting have different ballistic trajectory.
  • the reticle image used in a reflex sight is just one red or bright orange light spot.
  • a cross line, a light ring or other shapes are even used.
  • Their principles simply can not be adopted to set a reticle scale based on ballistic trajectory.
  • the design of a reticle also follows the traditional one, at most presetting or downloading some reticles, but never mentioning about how to adjust a suitable reticle according to different ballistic trajectories of different bullets.
  • One objective of the present invention is to provide an electronic firearm sight, which has a touch display screen used for adjusting and determining an accurate and proper reticle, so as to overcome the shortcoming of current technology.
  • the electronic firearm sight comprises a set of lens for capturing the optical image of an aimed object, an image sensor for converting the optical image into electronic signals, a processor for receiving the electronic signals from the image sensor and processing them and other data, a memory for storing different programs and data, and a touch display screen for the operation of adjusting and determining a reticle, once having received operation instructions from users, the touch display screen sending the corresponding information to the processor, and receiving and executing commands from the processor.
  • zoom lens in order to overcome the problem of not being able to view clearly long distance objects of existing sights, a set of zoom lens are used.
  • the creative combination of zoom lens and the image sensor allows the long distance object display very clearly on the screen, which not only gets the traditional telescopic sight out of turning the magnifying ratio ring to enlarge images, but also fills in the blank of existing electronic sights, which use the digital magnification with the most magnification ration of 4 ⁇ .
  • the present invention further comprises a rangefinder, which is for detecting and measuring the distance between the aimed objects and the sight itself, and transmitting corresponding data to the processor. These data are used, as one of parameters, for the processor to analyze the location of a bullet impact point and the reticle.
  • the present invention further comprises a wind speed & direction sensor connected with the processor for detecting the speed and direction of wind, to detect the crosswind and the wind speed, and transmitting corresponding data to the processor. These data are used, as one of parameters for the processor to analyze the location of the impact point and the reticle.
  • the touch display screen comprises a touch screen, a display and a display driver.
  • the touch screen comprises a touch detection part and a touch controller.
  • the touch display screen is connected with a processor, which in turn is connected with a memory; the memory has presaved a Cartesian coordinate system, ballistic trajectory data based on different bullets, and reticle shapes based on the trajectory data of different bullets; once having received operation instructions from users about adjusting the reticle, the touch display screen sends corresponding information to the processor; once the processor finishing data analysis and forming commands, the touch display screen receives the commands and executes them.
  • the touch display screen is connected with an operation panel.
  • operation panel On the operation panel are set operation buttons for controlling the Cartesian coordinate system and reticle scales of the trajectories formed based on different bullets, locking the image of aimed objects, and zooming in or out the image.
  • Another objective of the present invention is to provide a method of using the touch display screen described above to adjust and determine the reticle of an electronic firearm sight, so as to overcome the shortcomings of current technologies, which preset a rated value as the basic value per unit movement of the reticle.
  • the method comprises the following steps:
  • the method described above further comprise the steps, after determining the place of the reticle, that choosing a proper reticle shape based on the bullet type, the color and brightness of the reticle, and the requirement for lines. These steps can be operated through an operation panel.
  • the present invention has the following advantages.
  • the users can simply click the actual bullet's impact point displayed on the screen, instead of using the rated movement scale of the reticles of the existing technologies. Therefore, it can fulfill real accurate superimposition of a reticle and a bullet impact point, and eventually improve the aiming accuracy greatly;
  • the optically amplified object can be displayed very clearly on the screen, thereby opening up a new time of big magnification sight. It is enormous to use a sight with the magnification rate of 36 ⁇ , or even 100 ⁇ in the practical shooting, compared to the at most 4 ⁇ digital zoom of current electronic firearm sights and at most 8 ⁇ of telescopic sights.
